IPC: B65G1/04
Filed: 1996-04-30
Abstract: PROBLEM TO BE SOLVED: To enable the prevention of a horizontal swing of a cable even in the case where a carriage is moved up and down at a high speed by extending a wire on a side of a mast in a vertical direction and allowing the wire to pass through a guide post to guide an up and down movement of the guide pipe which movement is resulted from the up and down movement of the carriage. SOLUTION: A drum 29 has a rotation shaft 31 and a pair of guide pipes 32 and 33 are fixed to both side of this rotation shaft 31 via a metal fixture. The guide pipes 32 and 33 are formed of steel or a resin, and has an inside diameter larger than the diameters of the wires 21 and 22, and these wires pass through the inside of the guide pipes 32 and 33 corresponding thereto. Consequently since the guide pipes 32 and 33 are guided by the wires 21 and 22 and moved, the drum 29 smoothly falls together with the guide pipes 32 and 33. Consequently, the horizontal swing of the flat cable 11 and the projection of the mast to the side can be prevented.

Title: Misfire detector
Inventor: AOYAMA TOSHIHIKO
IPC: F02B77/08
Filed: 1980-08-09
Abstract: PURPOSE:To improve misfire detection in stability and reliability, by measuring the lowering of the exhaust  temperature and resulting from a misfire. CONSTITUTION:Thermocouple temperature detectors 1A and 1B are attached near the exhaust ports of respective cylinders of an internal-combustion engine, one for each of said cylinders. The ends 2A and 2B of the  thermocouples, having the same polarity, are connected together, while the ends 3A and 3B having the opposite polarity are connected across an exciting coil 5 of a reed relay 4. An auxiliary exciting coil 6 is wound on the  outside of the exciting coil 5,and a power source whose current direction changes every given time is connected  across said coil 6. When there is no misfire, the temperature in the respective cylinders are approximately equal  to each other, so that the electromotive forces of the respective thermocouples 1A and 1B are approximately  equal to each other. When there is a misfire, however, a large temperature difference, approximately 500 deg.C,  arises between the insides of the respective cylinders. Consequently, an electromotive force difference arises, so  that a current flows in the exciting coil 5, from the 3B side to the 3A side. When said current direction and the  current direction changed over by a timer 8 coincide with each other, the magnetic force increases, so that a reed  switch 7 is closed to turn on a lamp 11. When the circuit is changed over after a given time by means of the  timer 8, the current direction of the auxiliary coil side is reversed, so that the switch 7 is opened to turn off the lamp 11, which repeats on-off operation thereafter.
